On the last episode of “Teen Mom 2,” Jenelle met with her lawyer, who shared his expectation that the drug charges against her would be reduced. It was a huge relief to the recovering addict; however, the news that Jenelle’s ex, Courtland, would soon be released from jail was anything but.

In this sneak peek of Tuesday’s episode, Barbara and Jace pay a visit to Jenelle while she’s recovering from appendix surgery, and what starts off as a sweet reunion complete with a bouquet of flowers turns into a screaming match between Barbara and Nathan.

After Barbara warns the couple to stay off the roads for fear that Courtland might be back in town and looking to pick a fight, she implies that Nathan — like Jenelle’s other boyfriends — will wreck her daughter’s car, which immediately sets Nathan off. As he defends himself against previous claims that he’s a “bulls**t liar” and a “pretty boy,” Barb prepares to storm out the door, but not before Nathan strikes one final low blow.

“You’re a great parent, you got your daughter hooked on heroin,” he yells. “Good job, Barbara!”

“I didn’t put a needle in her arm!” Barbara screams back. And it doesn’t end there…

Check out the clip, and tune in to “Teen Mom 2″ Tuesday at 10/9c to see if Jenelle can keep the peace between Barbara and Nathan.
